    (54) Electrophotographic photosensitive materials


    (57) This invention provides an electrophotographic photosensitive material comprising a conductive support having thereon a photoconductive layer containing at least an inorganic photoconductor and a binder resin, wherein the photoconductive layer contains an N-hydroxyimide compound represented by the following general formula (I):


    wherein Z represents an organic residue capable of forming a cyclic compound having a saturated or unsaturated bond, thereby increasing its photosensitivity and improving its chargeability, dark charge retentivity and photosensitivity over a wide range from visible to infrared regions. Upon actual reproduction, the inventive material provides a fog-free and clear image even under severe conditions such as hightemperature and high humidity conditions (e.g., 30 °C and 80 % RH).
